The PTS is too small to hold multiple campaigns, and I doubt the devs would want to ditch the campaign that has no restrictions and can be tested with the lag issues of vet pvp for the pre-vet already-pretty-balanced campaign. Maybe they've done stuff internally, but I highly doubt we'll get to test anything for the non-vet campaign.

More balanced than Vet PvP sure, but it's not balanced completely. The fact that people can roll their Champion points down to non-vet characters and have that apply in the Non-vet PvP servers does make it pretty unbalanced depending on the individual enemy.
